Polymer beads have been used as the core of magnetic particles for around twenty years. Here we report studies to attach polymetallic complexes to polymer beads for the first time, producing beads of around 115 microns diameter that are attached to 10 hybrid inorganic-organic [2]rotaxanes. The bead is then formally a [10] rotaxane. The number of complexes attached is counted by EPR spectroscopy after including TEMPO radicals within the thread of the hybrid [2]rotaxanes.
聚合物珠粒作为磁性颗粒的核心已被使用了大约二十年。在此,我们首次报告了将多金属配合物附着到聚合物珠粒上的研究,制备出了直径约为115微米的珠粒,这些珠粒附着有10个无机 - 有机杂化的[2]轮烷。该珠粒进而正式成为一个[10]轮烷。在将TEMPO自由基引入杂化[2]轮烷的链中后,通过电子顺磁共振光谱法计算附着的配合物数量。
